Specification of Letters Patent.

Serial No. 732,579.

To all whom it may concern Be it known that I, SVEN E. GREEN, citizen ofthe United States, residing at Bristol, in the county of Hartford andState of Connecticut, have invented certain new and useful Improvementsin Tool-Holders, of which the following is a, specification.

One object of the invention is to provide means for positively adjustinga tool holder so that the tool holder thereby may be arranged inaccurate position.

A further object of the invention is to provide positive means for bothadjusting and locking the tool holder.

To these ends and also to improve generally upon devices of the'classspecified the invention consists in the matters hereinafter describedand claimed.

Figure -1- is a perspective view of the tool holder base. Fig. 2 is anelevation partially in cross section of the invention. Fig. -3- is alateral view of Fig. 2- partially cut away.

Referring to the drawings as the illustrated embodiment of theinvention, -1 is a longitudinally movable member having a transverseslot as at -2 therein. The said slot preferably has an enlargement atthe bottom thereof extending across said movable member 1-. A toolholder base 3 is mounted on said longitudinally movable member 1- andhas a lug ---4 adapted to travel transversely to said longitudinallymovable member in said slot 2. The lug 4r is preferably pierced as at -5and threaded to receive the threaded end of a bolt -6- preferablysecured to said movable member -1-- by means of a plate -7 which isslotted as at -8- to engage an annular groove 9 in the bolt -6. It willthus be seen that by turning said bolt 6- in either direction the base'3- and the tool holder 10- may be adjusted laterally as desired. Thetool holder 10- preferably is loosely mounted on said. tool holder base-3- and may be moved. slightly on said base 3 by means of an eccentricbolt 11 in engagement with an opening 12 in said base.

To secure said tool holder and said tool holder base in the desiredposition I provide the following locking means: An upright shank 13extends through an aperture as at l4 in said base and through saidmovable member,

tool holder -10- so that it may be tightened up or loosened by means ofa nut -14t-. The lower end of said shank has an enlarged head -15 whichtravels laterally in the enlarged bottom portion of the slot -2 when thetool holder is given the lateral adjustment. As the head 15 and the lug4- are preferably a fixed distance from each other and are preferablyarranged snugly in the said slot 2, when adjusting the device steadinessand accuracy may be accomplished thereby. The head 15- is preferablysquare and when the nut -14- is tightened up it comes into positiveengagement with the sides of the transverse slot 2 and when the nut -1lis set both the tool holder 10 and the base 3-- are positively held inposition thereby.

A tool may be held by said tool holder in any manner desired "butpreferably I provide an opening 16- therein to hold any such tool.

What I claim is 1. In a device of the class specified a longitudinallymovable member having a transverse slot, a tool holder base mountedthereon having a lug slot, said lug belng in threaded engagement with abolt secured to said longitudinally whereby said tool holder base ismoved laterally as desired and an upright locking member extending fromsaid slot through said tool holder base having its head traveling insaid slot.

2. In a device of the class specified a longitudinally movable memberhaving a transverse slot enlarged at the bottom thereof, a tool holderbase mounted thereon having a lug adapted to travel in said slot, saidlug being in threaded engagement with a bolt secured to a plate on saidlongitudinally movable member, whereby said tool holder base is movedlaterally as desired and an upright locking member extending from saidslot through said tool holder base having its head traveling in saidslot with said lug.

3. In a device of the class specified a longitudinally movable memberhaving a transverse slot, a tool holder base mounted thereon having alug traveling in said slot, means for transversely moving said base onsaid slot and a locking member having its head traveling in said slot.

4:- In a device of the class specified a lonadapted to travel in saidgitudinally movable member having a trans- In testimony whereof I afiixmy signature verse slot, a tool holder base mounted therein presence oftWo Witnesses. on having a lug traveling in said slot, means fortransversely moving said base on said SVEN GREEN 5 slot and a lockingmember having its head Witnesses:
